Описание
An authenticated SSH client that repeatedly opened channels which were rejected by the server caused unbounded memory growth, eventually crashing the server process and affecting all connected users. Rejected channels are now properly removed from the connection's internal state and released for garbage collection.
A flaw was found in golang.org/x/crypto/ssh. An authenticated SSH client can cause a Denial of Service (DoS) by repeatedly opening channels that are rejected by the server. This leads to unbounded memory growth, eventually crashing the server process and affecting all connected users.
